The hydropower development in the Aurland Valley is an elegant network of dams, tunnels and power stations. The same water is used several times as it passes through the various power stations on its way from the high mountains to the bottom of the fjord.
Aurland I is E-CO Energi's largest power plant and is the second lowest in the Aurland watercourse. The power plant uses a height of fall of 870 metres from the reservoir Lake Viddalsvatn.
The construction of this power plant has occurred in several stages. The first stage began in 1969 and the first generating unit was commissioned in 1973. In 1975 another unit was added, and in 1989 the station was completed with three generating units.
Between 2004 and 2006, all three units were upgraded from 225 to 280 MW.
All three generating units are equipped with Pelton turbines. Average annual production is 2015 GWh.
E-CO Energi AS is the operator of Aurland I power plant and responsible for daily operation.
